This is a gem of a product made by Nitro Vo. The vertical foregrip has become a mainstay of the M4 / M16 community. Originally designed to keep the shooter’s hands away from the heated barrel of a real steel rifle, the vertical foregrip also has been found to allow for greater maneuverability in close quarters action. The Nitro Vo Folding Vertical Foregrip is a real functional piece of kit, as it allows for quick maneuvering of the weapon in tight quarters, and can be tucked away when not needed. This foregrip is not for everyone however, as your play style will contribute to how useful it is
